On June 29, 1988, the Douglas Research Conservatory was dedicated. It was a state-of-the-art facility for plant propagation, research, and horticultural education.

Tucked away behind the Cedrus knoll in the Arboretum’s Pinetum is the Euonymus europaeus ‘atrorubens’. At this time of year it is showing off its colorful seed pods, which hang all over the defoliated branches. A plant that has pink and orange fruits really catches your eye when you pass by.
This shrub is native to Europe and Western Asia and its common names are Spindle Tree and Cat Tree. 

Yew, willow and witch hazel are just a few of the woody plants at the Arboretum with medically important characteristics.

Local photographer and avid birder, Larry Hubbell, experiments with drawing bird portraits up close and personal. Viewers get the impression birds are doing the watching.

In preparation for scheduled landscaping work on Foster Island Washington Department of Transportation will conduct archeological evaluations on Wednesday, December 18.

1)   Abies balsamea   (Balsam fir)
